CAR REGISTER.

Application filed August 5, 1921.

To all whom it may concern.-

Be it known that I, FRIEDRICH ZIMMnre MANN, residing at Essen, Germany, a citizen of the German Republic, have invented a certain new and useful Improvement in Car Registers, of which the following 1s a specification.

This invention relates to apparatus adapted to register the number of carspassing over a track. Its object is to eliminate the possibility of a fraudulent registration by such an apparatus.

An embodiment of the invention is illustrated by way of example in the accompanying drawings in which:

Fig. 1 is a longitudinal section of the apparatus, buil nto a railroad track, showing a miners truck on the track,

Fig. 2 is a plan view of the structure illustrated in Fig. 1, with the truck omitted,

Fig. 3 is a section on line 3-3 of Fig. 2 looking from the right, and

Fig. 4C is a section on line 44 of Fig. 2 looking from the right, with, however, the truck as shown in Fig. 1.

Onv a box-like casing A which is secured on the ties B of a railway track C C there is pivoted on a bolt D a swinging plate E, the width of which, measured in the direction of the track, is greater than the distance between the outer axles of the cars running on the track C C In the illustrated example, the width of the plate E is greater than the distance f between the axles of the truck F.

The swinging plate E engages with its free end. in a recess 0 formed laterally in the head of one of the rails, C, which recess limits the swinging movement of the plate E in the direction of the arrow as, Fig. 3. Adjoining the lateral recess (3 there 18 provided in the head of the rail C a trough shaped recess 0 so that the wheels of the truck F running on the track C C when entering the said recess 0 act upon the plate I in the direction of the arrow 0;, the weight of the truck tending to cause a rotation of the plate E in said direction. Such rotation is resisted, however, by a spring G (see Fig. 3), the strength of which is such that the plate E can only swing in the direction of the arrow 00 when all of the axles of the car, inthe present case both axles f of the truck F, are supported by Serial No. 490,1 14.

the plate E. This is made possible by dimensioning the plate E as stated above.

On the plate E is mounted a movable pin J, acted upon by a spring H (see Fig. 4). Upon movement of the plate E, in the direction of arrow w, the pin J is caused to contact with a'circuit closer K whereby an electrically operated counting mechanism (not shown) is actuated. This contact is accomplished without compressing the spring H completely. Consequently, further movement of the plate E does not affect the pin J, this movement being compensated for by the spring H, thereby protecting the circuit closer K against damage by shocks.

Between the rails 0 C adjoining the plate E, there is mounted in a casing M, a series of four turnstiles N, of the shape of Maltese crosses, so that they project with one of their arms into the path of the truck axles f (see Figs. 1 and 4). For each turnstile N a pawl P is provided, so arranged that it yields when the turnstile N is turned in a clockwise direction (see Fig. 1) against the action of a spring Movement of the pawls in the opposite direction, and consequently of the turnstiles N is prevented by fixed stop pins 772}. A truck can, therefore, run only in the direction of the arrow .2 (Fig. 1) over the turnstiles N and therewith over the plate E. The turnstiles N are so located, that, when the truck F is standing on the plate E (see Fig. 1), the truck F is prevented by some of the turnstiles N from being pushed down from the plate E in a direction opposite to that of the arrow 2. Alsg any movement of the truck F onto the plate E from the right in Fig. 1, is prevented by the turnstile N farthest to the right. Consequently a truck can only be run once over the plate E and that in the direction of the arrow 2. It consequently follows that it is impossible to accomplish a double count ing of a truck by running it back and forth over the plate E.

The operation of the above described de-' vice can be readily understood from the foregoing and need not be further described.

Having thus described my invention, what I claim is:

1. In a car registering apparatus, means adapted to be engaged by the car for preventing movement of the car in one direction, a member adapted to be actuated by Q naaasee beyond both sides of said member.

3. in acar registering device a ratchet device projecting into the path of the car for preventin;- movement of the car in one direction, an operating member mounted adjacent the track and enabled to engage all the Wheels on one side of a car, said operating member being); so shaped and arranged that it will function only when acted upon by all of the Wheels On one side of a car and means controlled by said operating member for actuating; a counting mechanism, said ratchet device extending beyond both sides of said operating member in the direction of the track.

4. In a car registering apparatus a ratchet device projecting into the path otthe car for preventing movement of the car in one direction, an operating plate pivotally mounted adjacent said track and adapted to be actuated by the Wheels of the car, said plate being of such a dimension as to permit simultaneous engagement of all the Wheels on oneside off a car, means preventing actuation of said plate until engagement oi all of the wheels is effected and means controlled by said plate for actuating a counting mechanism, said ratchet device extending beyond both sides of said operating plate. p

The foregoing; specification signed at Essen, Germany, this 2nd day of July, 1921.
